HP-2136color difference

colorimeterUsage in daily production

Firstly, measurement of color grading

When users receive a sample, they need to reproduce the same color as the sample, which requires repeated sampling. Previously, the difference between the small sample and the standard sample was compared by the human eye. When it is within the allowable range, the process is handed over to the workshop for production Due to subjective factors of the human eye, it is difficult to determine the difference. In this case, a colorimeter can be used to measure the difference between the sample and the standard sample, and the color difference of the sample can be determined based on the difference to determine whether the color difference of the sample is within the range. This can reduce the uncertainty of human eye observation. The biggest advantage of using a colorimeter to participate in color matching is that it can correct the formula based on the data provided by the colorimeter and reference the color chart, which can complete the color matching task faster and more accurately

Secondly, its role in quality control

After the formula is determined and put into production, due to various factors in production, batch products may have color deviation. Therefore, it is necessary to frequently use a colorimeter to measure color deviation in production to adjust the production process and achieve product color consistency

Thirdly, in terms of quantity transmission

Customers nowadays usually provide color cards or samples, so when signing contracts with users, it is best to preserve the physical object as a standard. Even the most high-end instruments may have deviations according to the actual environment. The national color standards are based on standard whiteboards and color palettes, not instruments.

usage method:

1Remove the lens protective cover.

2Turn on the power to the ON position.

3Press the sample target key TARGET once, and Target L a b will be displayed.

4Align the lens with the tested part of the sample, press the input button, and wait for a beep before moving the lens. At this point, the absolute value of the sample will be displayed: Target L**.* a +-**.* b +-**.*。

5Align the lens with the tested part of the object to be tested, repeat the testing work in point 4, and display the color difference value between the tested object and the sample: dL **.* da +-**.* db +-**.*。

6According to the working principle described earlier, determine the magnitude and direction of color difference between dL, da, and db.

7Repeat points 6 and 7 to detect color differences between other tested items and the sample in point 4.

8If you want to resample, you need to press TARGET at 4 o'clock
